Hello everyone. Just bought a low miles CPO '11 X3 2.8. I noticed in the trunk area, there is a lid/cover that cover some storage "compartments" underneath with very specific and unique shapes.

Can someone tell me what came in these compartments originally?

Also, have a lighted USB charger and noticed that even after killing the engine, exiting the vehicle, and locking the doors, power is still live in both the cig lighter next to the cup holders as well as inside the console. Is this normal? Will the power get cut after a specific delay? Was too afraid to leave the USB charger plugged in in case it malfunctioned/overheated and started a fire.

And one final question... I don't have the tech package (ie. no nav). Can the USB port inside the console be used to play music off a USB thumb drive? I know they have a Y-cable to hook up certain model IPods. Was hoping I could play stuff off the USB port or use the 3.5mm jack as audio in. Are either possible?

Thanks for the answers. Regarding the cig lighter, never seen a delayed off on any of my previous cars so this is new to me. I'll have to check it out.

I have the Y-cable on order but was hoping someone knew if it could either play stuff off a USB thumb drive or take an audio in from another device via the 3.5mm jack. I've tried the USB thumb drive but couldn't find where to switch to that input. Guessing playing off a USB thumb drive is a no go. Have not tried audio in via the 3.5mm jack although I don't see where to switch to this in idrive either. Anyone know for sure?

If you were listening on the radio, don't you have to "switch" to the 3.5mm jack for the speakers to start playing it? Or is the system such that if it detects any audio coming in from this jack, it takes precedence and automatically switches to it? I guess I'll try this out when I get home.

In my other vehicles, I have to switch to the aux input to start listening to stuff ont he 3.5mm jack.

You need to hit the CD button and there you select External Devices, it should have a check mark beside it when the device is plugged in through a 3.5mm cable.
